Description

Technical Field

[0002] The truck head refers to the front part of the truck, which contains the cab, engine, steering system and other mechanical and electronic components necessary to control the operation of the vehicle. The truck head is usually connected to the trailer through the fifth wheel coupling device (also called a turntable or gooseneck) behind the cab, allowing the truck to tow different trailers. Depending on the type of truck, the design and size of the head will also vary. For example, there are many types such as heavy trucks, semi-trailer tractors, and dump trucks. In addition, during the production process of the truck head, the surface of the head needs to be painted to prevent corrosion and improve the appearance. During the spraying process, the truck head is generally suspended by a gantry crane device to the paint booth for painting.

[0003] However, when the existing suspension device is used to clamp the truck head for transportation and spraying, the area of ​​the clamped truck head is occupied by the clamping structure, so that the occupied area cannot be sprayed on the paint surface, so that the user needs to place the truck head back on the ground or on a docking device for processing, and restart the suspension device to clamp the truck head, and clamp other areas that have been sprayed and re-suspend them, and then transport them to the paint room for painting. This method undoubtedly increases the user's workload and increases the working time of painting, which is time-consuming and labor-intensive, reduces the work efficiency of painting the truck head, and is inconvenient to use. Therefore, we propose a truck head production and painting suspension device with easy-to-use functions, which is urgently needed to be developed. Utility Model Content
